“This music course is excellent. It doesn’t matter what level you are at in your instrument (or even if you don’t play any instrument); this course is an effective introduction to music theory. If you have ever wanted to gain an understanding of why music works the way it does, or if you want to learn how to write your own music, this is where you should start. And even if you already have some understanding of music theory, it will fill in any gaps in your knowledge. Highly recommended!”
